City Council approval requires a simple majority vote of the City Council present." At the June 22, 2015 work session, staff reviewed with Council the proposed 2016 Street Improvement project areas. Staff also discussed with the Council the need to make improvements to more local streets then are currently budgeted for in the capital replacment plan. Every year the City considers streets that are in poor condition to be rehabilitated or reconstructed. At the August 24, 2015 meeting, the City Council approved a contract with WSB & Associates for the reconstruction of 1.1 miles of streets within the Minnewashta Manor neighborhood located on the north side of Lake Minnewashta. This work is proposed to be completed under City Project No. 16-01. Website The proposal for City Project No. weimuchanhassen.unn.us 16-05 includes the rehabilitation of approximately 1.4 miles of rm vim Nn R ciw�xr orlw � -- r MoupMm Avenue streets. The street segments within the proposed project were identified by the City's Pavement Management software in conjunction with site investigations and are shown on the adjacent graphic.

Severe pavement distresses will be removed and replaced. Minor drainage improvements are also proposed to be addressed in the project areas. Water main gate valve and hydrant bolt replacements are proposed for replacement in these areas. A feasibility report will be prepared by the Engineering Department staff. The anticipated project savings will be between $85,000 and $100,000 if feasibility report preparation, design and construction observation are not outsourced. Proiect Area #1: Lone Cedar Area Approximately 0.4 miles of urban streets are proposed to be milled and overlaid within the Lone Cedar neighborhood located north of Highway 5 and east of Minnewashta Parkway. The streets in this area are 39 years old and were sealcoated in 1994, 1999 and 2008. The street conditions in this area were last surveyed in 2014. The Pavement Condition Indices (PCIs) from the survey are shown on the map to the right. A PCI below 45 typically warrants reconstruction; however, the utilities in the area are in fair condition and therefore staff is recommending a full depth mill and overlay of the streets at this time. Subgrade corrections would be done as needed. The sanitary sewer system in this area will be televised to determine the scope of sanitary sewer repairs. The water main in this area is ductile iron. City records do not show any water main breaks in this area. It is recommended to replace the bolts on the valves and some hydrants at this time. Storm sewer exists within the project area. No additional storm sewer is proposed with this project. The existing infrastructure will be surveyed to determine if any repairs are necessary. Budgets for the proposed work were included in the proposed 2016 CIP. The budgets will be reviewed and updated based upon current construction cost estimates. Project Area #2: Fox Path Area This project area consists of 0.6 miles of urban streets south of Pleasant View Road and west of the northern tip of Lotus Lake. The streets in this area are 30 years old and were sealcoated in 1993, 1998 and 2007.

Properties in this area are serviced by ductile iron water main. There was one documented water main break in the area on Lake Point in 2013. It is recommended to replace the bolts on the valves and some hydrants at this time. Storm sewer exists within the project area. No additional storm sewer is proposed with this project. The existing infrastructure will be surveyed to determine if any repairs are necessary. Project Area #3: Ches Mar Drive Ches Mar Drive is a 0.2 mile rural residential street on the west side of Highway 41 near Lake Minnewashta Regional Park. This street was constructed in 1960. There are no records of sealcoats on this road. Ches Mar Drive was surveyed in 2014 and the PCI was 13, therefore a full depth mill and overlay is proposed for this road. The properties that access Ches Mar Drive are not serviced by City sanitary sewer or water. There is no storm sewer in the area. No storm sewer improvements are proposed with this project. Project Area #4: Stoughton Avenue Stoughton Avenue is a 0.2 mile street in the southwest corner of the City, extending west from Flying Cloud Drive and into the city of Chaska. This street was constructed in 1950 and overlaid in 1999. The street was surveyed this year and the PCI is 33. Stoughton Avenue is a Municipal State Aid street and is eligible for funding from the State. Staff is not recommending using State Aid funds for G:\ENG\PUBLIC\_2016 PROJECTSV 6-05 2016 Street Resurfacing Project\Co=uniwion\20151026 order feasibihty.docx Paul Oehme 2016 Street Rehabilitation Project October 26, 2015 Page 4 this project given the small scope of this project; there are other, larger scale MSA routes such as Park Road for which the City will pursue State Aid funding. The City of Chanhassen does not have public sanitary sewer or water main in this area. The City of Chaska provides sanitary sewer and water service to Gedney Pickle, which is located west of the project area. The remaining properties in the area within the Chanhassen city limits are serviced by well and septic systems. There are no storm sewer improvements within the project area. There are no storm sewer improvements proposed with this project. PROJECT FUNDING Forty percent (40%) of the street improvement cost would be assessed back to the benefiting property owners, per the City's assessment practice. The remaining 60% of the street costs would be a City cost. Each project area would have its own proposed assessment. Any storm sewer, sanitary sewer and water main improvements replacement costs would be funded by the respective utility funds in the annual utility budgets.

While proper preventative maintenance extends the life of the street and is cost effective, a street will eventually deteriorate to a point that further maintenance is no longer cost effective. Rehabilitation projects extend the life of the street. In cases when utilities or poor sub grade needs to be replaced or where streets have deteriorated to a point where rehabilitation will no longer be practical, reconstruction of the street is necessary. A feasibility study is written to consider the merits of the project and scope of work. Highway 212 improvement project included a pedestrian trail along the first 2,500 feet of Bluff Creek Drive. The resulting "gap" represents a ing link in the City's trail system south to Flying Cloud Drive. Bluff Creek Drive is a difficult stretch of road to negotiate as a pedestrian in Ibsence of a trail. This trail segment is planned to be constructed along with the 2017 MSA street reconstruction.
